How about a DC motor, in a rotating reference frame? Best regards, Spehro Pefhany -- "it's the network..."

I see Sunworshipper around once in a while. Pete still doing automotive journalism? Does he have a public blog or is it a private haven for curmudgeonly activities? I miss Mr. Mulligan (ex IBM ?). He once called a few of us 'Alpha' males. I told him I was 'Beta 0.009' at best. mike

The Faraday disk is weird. I didn't expect statement 2 or 3. So much for relative motion. ========================================= 1. The magnet is held to prevent it from rotating, while the disc is spun on its axis. The result is that the galvanometer registers a direct current. The apparatus therefore acts as a generator, variously called the Faraday generator, the Faraday disc, or the homopolar (or unipolar) generator. 2. The disc is held stationary while the magnet is spun on its axis. The result is that the galvanometer registers no current. 3. The disc and magnet are spun together. The galvanometer registers a current, as it did in step 1. http://en.wikipedia.org/wiki/Faraday_paradox ========================================= mike |
